RENEWCONNECT - All about renewables & power sector

Some of the key critical components that are used in the Transmission System:  Power Generating Stations The source of electricity (thermal, hydro, nuclear, solar, wind, etc.). Electricity is generated at relatively low voltages (e.g., 11–33 kV). Step-Up Transformers Increase the voltage to high levels (e.g., 132 kV, 220 kV, 400 kV, or higher) for efficient long-distance transmission. Located at generating stations. Transmission Lines High-voltage overhead or underground lines that carry electricity over long distances. Typically made of aluminum conductors reinforced with steel (ACSR). Transmission Towers / Poles Support overhead transmission lines. Designed to maintain safe clearance and withstand environmental conditions. Substations Intermediate stations that monitor, control, and route electricity. Include equipment like transformers, circuit breakers, isolators, and protection systems. Step-Down Transformers Reduce voltage levels for distr...

Feeder lines  and  Substations  are not the same—they serve different but complementary roles in the electrical power distribution system. Here's a breakdown of each: 🔌  Feeder Line A  feeder line  is a power line that  carries electricity from a substation to distribution transformers  or directly to end users. It is part of the  distribution network . Typically operates at  medium voltage  (e.g., 11kV, 33kV). It does  not  generate or transform power—it simply  transports  it. 🏭  Substation A  substation  is a facility where  voltage is transformed  from high to low (or vice versa) using transformers. It connects  generation stations  to the  transmission and distribution networks . Substations can include: Power transformers Circuit breakers Busbars Protection...
